(specific heat capacity of zinc is 390 J / kg C) 15. 6.1.4 The objective is to apply the concept and formula in solving problemsQuestion 2 150 g of water is at 140C. How much heat must be removed to lower the water to 75C ? (Specific heat capacity of water is 4.20 kJ / kgC 16. 6.1.4 The objective is to apply the concept and formula in solving problemsQuestion 3 A 0.23 kg sample of Aluminum is provided with 4500 joules of heat energy. What will be the change in temperature of this sample? 17. CONCLUSION * TEMPERATURE is a Physical Quantity that measure DEGREE OF HOTNESS of a body. SI Unit = KELVIN (K) * HEAT is ENERGY (Therma) that FLOWS naturally from HOT body to COLD body. SI Unit = JOULE (J) HEAT TRANSFER methode is refer to CONDUCTION, CONVECTION & RADIATIONHEAT CAPACITY formula isQ = mc 18.
